On the critical time of observability of the multi-dimensional Baouendi-Grushin equation

Jérémi Dardé, Mathilda Trabut

We investigate the observability properties of the Baouendi-Grushin equation on a tensorized domain $\Omega :={\mathcal{B}}_R\times \tilde{\Omega }$, where ${\mathcal{B}}_R$ is the open ball of r…
